MAHLE 3011195 Performance Gas Nitrided Piston Ring Set Bore - 4.170

The MAHLE 3011195 is a high-performance piston ring set engineered for demanding racing and performance applications. This premium ring set features advanced gas nitrided steel construction for superior wear resistance and durability under extreme combustion pressures and temperatures.

Key Specifications:

• Bore Size: 4.170 inches
• Top Ring Width: .043 inches
• Oil Ring Width: .157 inches
• Ring Type: Plain (flat profile)
• Material: Gas nitrided performance steel
• Configuration: RW (reverse wound oil ring design)

Performance Features:

• Gas nitriding process creates an ultra-hard surface layer that resists scuffing and wear
• Optimized ring tensions for maximum sealing with minimal friction losses
• Precision-machined flat profile for consistent cylinder wall contact
• Engineered for high-RPM racing engines and forced induction applications
• Superior heat dissipation compared to standard chrome rings

MAHLE's gas nitriding technology provides exceptional ring life and maintains cylinder seal integrity throughout the engine's operating range. The thin top ring width (.043") reduces friction while maintaining excellent combustion sealing, making this ring set ideal for performance street engines and dedicated race motors requiring maximum power output and reliability.
